Mirra Voice

Voice call history, transcripts, and call metadata

Prerequisites

You need the user's API key. Ask for these if not provided:

• API_KEY: Mirra API key (generated in Mirra app > Settings > API Keys)
• API_URL: Defaults to https://api.fxn.world (only ask if they mention a custom server)

API Call Pattern

All operations use a single POST endpoint with the resource ID and method in the body:

curl -s -X POST "${API_URL}/api/sdk/v2/resources/call" \
  -H "Content-Type: application/json" \
  -H "x-api-key: ${API_KEY}" \
  -d '{
    "resourceId": "voice",
    "method": "{operation}",
    "params": { ...args }
  }' | jq .

Replace {operation} with the operation name from the table below.

Legacy alternative: POST ${API_URL}/api/sdk/v1/voice/{operation} with args as the request body also works but is not recommended for new integrations.

Operation Details

getCallHistory

List voice calls the user participated in, with filters for scope, status, and date range. Returns call metadata (no transcript content). Use getCallTranscript or getCallSummary to retrieve transcript text for a specific call.

Arguments:

• scope (string, optional): Filter by call scope: "direct" (1-on-1 with AI), "group", "user" (user-to-user), or "meeting" (public shareable). Omit to return all scopes.
• status (string, optional): Filter by call status: "active", "ended", "cancelled". Defaults to all statuses.
• groupId (string, optional): Filter calls to a specific group by group ID.
• startDate (string, optional): Filter calls created on or after this date (ISO 8601, e.g. "2025-01-15T00:00:00Z").
• endDate (string, optional): Filter calls created on or before this date (ISO 8601).
• limit (number, optional): Maximum number of calls to return (default: 20, max: 100).
• offset (number, optional): Number of results to skip for pagination (default: 0).

Returns:

AdapterOperationResult: Returns { data: { count, offset, limit, calls[] } }. Each call has: id, agoraCallId, scope, status, createdAt, endedAt, durationMs, participantCount, videoEnabled, meetingTitle.

Example:

curl -s -X POST "${API_URL}/api/sdk/v2/resources/call" \
  -H "Content-Type: application/json" \
  -H "x-api-key: ${API_KEY}" \
  -d '{"resourceId":"voice","method":"getCallHistory","params":{"status":"ended","limit":5}}' | jq .

      "status": "LEFT"
    }
  ]
}

getCallTranscript

Get transcript segments for a voice call. Each segment contains the speaker, text, timing, and confidence. Results are sorted by time. For a human-readable summary instead of raw segments, use getCallSummary.

Arguments:

• callId (string, required): The agoraCallId or MongoDB _id of the call.
• mirraTriggeredOnly (boolean, optional): If true, return only segments where a Mirra voice command was detected. Default: false.

    }
  ]
}

getCallSummary

Get a human-readable formatted transcript summary for a voice call. Returns speaker-attributed text in "Speaker: text" format. Useful for AI context, summaries, and recaps. For raw segment data, use getCallTranscript instead.

Arguments:

• callId (string, required): The agoraCallId or MongoDB _id of the call.
• maxLength (number, optional): Maximum character length of the summary (default: 2000). Transcript is truncated with "[Transcript truncated...]" if it exceeds this.

Returns:

AdapterOperationResult: Returns { data: { callId, summary, characterCount } }. The summary is a formatted string with "Speaker: text" lines.

Example:

curl -s -X POST "${API_URL}/api/sdk/v2/resources/call" \

  "callId": "call_1750459861273_qbhg8we",
  "summary": "alice: Hey, let's discuss the Q2 roadmap.\nbob: Sure, I think we should prioritize mobile performance.\nalice: Agreed. Let's also look at the onboarding flow.",
  "characterCount": 158
}

searchTranscripts

Full-text search across transcript segments. Searches the text content of all transcripts the user has access to. Results include the call context and matching segments.

Arguments:

• query (string, required): Text to search for in transcript content (case-insensitive substring match).
• groupId (string, optional): Limit search to transcripts from calls in a specific group.
• startDate (string, optional): Only search transcripts from calls created on or after this date (ISO 8601).
• endDate (string, optional): Only search transcripts from calls created on or before this date (ISO 8601).
• limit (number, optional): Maximum number of matching segments to return (default: 20, max: 100).

Returns:

AdapterOperationResult: Returns { data: { query, count, results[] } }. Each result has: segmentId, callId (agoraCallId), speakerUsername, text, startMs, confidence, callCreatedAt.

Example:

curl -s -X POST "${API_URL}/api/sdk/v2/resources/call" \
  -H "Content-Type: application/json" \
  -H "x-api-key: ${API_KEY}" \

      "callId": "call_1750459861273_qbhg8we",
      "speakerUsername": "alice",
      "text": "Hey, let's discuss the Q2 roadmap.",
      "startMs": 1200,
      "confidence": 0.95,
      "callCreatedAt": "2025-06-01T10:00:00Z"
    }
  ]
}

getActiveCall

Check if there is an active (in-progress) voice call in a specific chat or group. Returns call details if active, or an empty result if no call is in progress.

Arguments:

• chatInstanceId (string, optional): Check for an active call in a specific chat instance.
• groupId (string, optional): Check for an active call in a specific group. Provide either chatInstanceId or groupId.

Returns:

AdapterOperationResult: Returns { data: { hasActiveCall, call? } }. If active, call contains: id, agoraCallId, scope, status, createdAt, participantCount, videoEnabled.

Example:

curl -s -X POST "${API_URL}/api/sdk/v2/resources/call" \
  -H "Content-Type: application/json" \
  -H "x-api-key: ${API_KEY}" \
  -d '{"resourceId":"voice","method":"getActiveCall","params":{"groupId":"group_123"}}' | jq .

Example response:

{
  "hasActiveCall": true,
  "call": {
    "id": "6789abc",

    "createdAt": "2025-06-01T11:30:00Z",
    "participantCount": 2,
    "videoEnabled": false
  }
}

Response Format

All SDK responses return the operation payload wrapped in a standard envelope:

{
  "success": true,
  "data": { ... }
}

The data field contains the operation result. Error responses include:

{
  "success": false,
  "error": {
    "code": "ERROR_CODE",
    "message": "Human-readable error message"
  }
}

Tips

• Use jq . to pretty-print responses, jq .data to extract just the payload
• For list operations, results are in data.results or directly in data (check examples)
• Pass --fail-with-body to curl to see error details on HTTP failures
• Store the API key in a variable: export API_KEY="your-key"
